Takeoff systems aren't analogous to prototype development. I don't know you'd build a prototype plane that's feasible to take to market, without having deep knowledge about how planes are built.

Early design decisions matter. And you don't get to that realisation without dealing with legacy systems where some upstart made terrible decisions that you're now responsible for.
